The length of the scale model of the car is 120 cm
Working out the length of the scale model of the car.From the question, we have the following parameters that can be used in our computation:
Length of a car = 3.6 meters
We have the scale to be
Scale = 1 cm to 30 cm
This means that
Scale = 1 cm : 30 cm
using the above as a guide, we have the following:
Scale : 3.6 meters = 1 cm : 30 cm
So we have
Scale = 3.6 m * 1 cm/30 cm
Evaluate
Scale = 0.12 m
Convert to cm
Scale = 120 cm
Hence, the length of the scale model of the car is 120 cm

Don bought 3/4 of a pound of jelly beans and ate 5/8 of the jelly beans before he got home. How much candy was left?
Answer:
CAN YOU MARK ME BRAINLIEST ??
The answer is 1/8 candy left!!
Step-by-step explanation:
3/4=6/8 because x2.
6/8-5/8= 1/8
Answer:
1/8 of the jelly beans
Step-by-step explanation:
You need to create a common denominator between the two fractions. Since both 4 and 8 go into 8, that will be the common denominator. To get 4 to 8, you have to multiply by 2, so to even it out you multiply the numerator by 2(3x2) which equals 6. Now the first fraction is 6/8 and the second is still 5/8. If he ate 5/8 of 6/8 jelly beans, you need to subtract. 6/8 minus 5/8 is 1/8

Lisa and Molly are on a bridge and see a tree sticking out of the water. Use the diagram to determine how far away Lisa is from the tree in the water. Use appropriate units.
Answer:
26.5 ft
Step-by-step explanation:
Let the point of the tree sticking out water be represented as S.
Thus, we have ∆LMS.
How far Lisa is from the tree in the water = [tex] \overline{LS} [/tex]
Using Sine Rule, find [tex] \overline{LS} [/tex]
[tex] \frac{\overline{LS}}{sin(M)} = \frac{\overline{MS}}{sin(L)} [/tex]
[tex] \overline{LS} = x [/tex]
[tex] \overline{MS} = 22 ft [/tex]
[tex] \angle M = 103 [/tex]
[tex] \angle L = 54 [/tex]
Plug in the values into the equation
Thus:
[tex] \frac{x}{sin(103)} = \frac{22}{sin(54)} [/tex]
Multiply both sides by sin(103)
[tex] \frac{x}{sin(103)}*sin(103) = \frac{22}{sin(54)}*sin(103) [/tex]
[tex] x = \frac{22*sin(103)}{sin(54)} [/tex]
[tex] x = 26.5 ft [/tex] (nearest tenth)
✅Lisa is 26.5 ft far away from the tree in the water.

Answer:
Volume of square pyramid=120,000 m³
Step-by-step explanation:
We are given: Base of square pyramid = 60 m
Height of square pyramid = 100 m
We need to find Volume of square pyramid.

Feeding the strawberry plants two times means
[tex]\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}[/tex]
Feeding the tomato plants one more time means
[tex]\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}[/tex]
The plant food he will need is [tex]5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}[/tex]

Solve the following equation by the quadratic formula. 9x 4 + 5x 2 - 4 = 0 {±2/3, ±1} {±2/3, ±i} {±4/9, ±1}
The solution of the equation by the quadratic formula are, {±2/3, ±i}
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The equation is,
⇒ 9x⁴ + 5x² - 4 = 0
Now, Put x² = y in above equation, we get;
⇒ 9y² + 5y - 4 = 0
Bu using quadratic formula as;
⇒ y = - 5 ± √5² - 4×9×- 4 / 2×9
⇒ y = - 5 ± √25 + 144 / 18
⇒ y = - 5 ± √169 / 18
⇒ y = - 5 ± 13 / 18
This gives two solution,
⇒ y = - 5 + 13 / 18
⇒ y = 8/18
⇒ y = 4/9
⇒ x² = 4/9
⇒ x = ±2/3
And, y = - 5 - 13 / 18
⇒ y = - 18 / 18
⇒ y = - 1
⇒ x² = - 1
⇒ x = ±i
Thus, The solution of the equation are {±2/3, ±i}.

The ratio of A to B is given by : [tex]\dfrac{A}{B}[/tex] or A : B .

Graph the function. I have provided a picture. First one to answer correctly will get Brainliest
Answer: Draw a straight line through (0, -4) and (2, -1)
Diagram is below
======================================================
Explanation:
The equation is in the form y = mx+b
m = 3/2 = 1.5 is the slope
b = -4 is the y intercept
The y intercept tells us where the graph crosses the y axis. In this case, it happens at (0,b) = (0,-4)
So (0,-4) is one point on the line.
The slope will tell us how to get to another point. Recall that
slope = rise/run
So we see that rise = 3 and run = 2 indicating we'll go up 3 and over to the right 2. Doing that will have you go from (0,-4) to (2,-1)
Therefore, the line will go through the two points (0,-4) and (2,-1) as shown in the diagram below. You can use more points, but two is the minimum number needed to graph a straight line.
---------------------
Another way to get points needed to graph this is to plug in various values of x. Let's say we plug in x = 0
y = (3/2)x - 4
y = (3/2)*0 - 4
y = 0 - 4
y = -4
We see that x = 0 leads to y = -4. So (x,y) = (0,-4) is one point on the line.
If we tried x = 2, then,
y = (3/2)x - 4
y = (3/2)*2 - 4
y = 3 - 4
y = -1
Showing (2,-1) is another point on the line. I didn't pick x = 1 since that would have led to a fractional value. It's easier to work with whole numbers in my opinion.
